OF PORTLAND, OREGON.

- LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 372,708, dated November 8, 1887.

Application filed J'uly 9, 18S?. Serial blo-243,908. (No model.)

To aZZ whom, it' may concern.:

Be itk nown that LJOHN C. SCHELLENBAUM, a citizen of the United Statesresiding at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Lubricators for Steam-Oylinders, of which the following is a specirication, reference being had therein to the accompanying drawing.

My inventionrelates to facilitating and economizing in lubricating steam reservoirs, cylinders, or chests7 and other steam-condensers, as the improvements consist of novel arrangements, allowing the oil or grease to find its way to the parts to be oiled by the force of water which forms in the cup by the condensation of the steam entering` the cup.

In the accompanying drawing I show a sec tional View of a lubricating-cup which fully illustrates my invention.

A is a glass tube forming the body and the oil-reservoir, and on account of being of glass a much easier control is gained bythe person in charge as to whether' a refilling is required or not. This glass tube A rests in the lower part, B, which also forms the connection part with the steam pipe or chest, whereas the top piece, O, is used as the cover of glass tube A, and resting on the same. The glass tube A may be protected,if necessary,by wires or wirenetting as an outside cover. rlhe nut E,which is screwed onto the upright stem b of lower part, B, rmly secures and fastens the different parts of the construction together. The plug D screws into the upright stern b, thus closing l the cup steam-tight. The lower part, B, and top piece, C, have flanges or shoulders a, to keep glass tube A and packing-rings a in their respective places. The lower part, B, with its upright stem b. is' made out ot' one piece,having a (l1'aii1-cock,d,and a steam-regulating valve, e, attached thereto. A channel, L, is drilled through lower part, B, and upright stem b large enough to allow the steam to enter through the smaller' channel,z',into condensingchamber r of upright stein b and into condensi11g-chamber k of plug D, from where the steam enters by means of holes 0, drilled through top of upright stem b, into the hollowed part k2 of top piece, O, and thence into the glass tube or reservoir A.

I am aware that prior to my invention lubricators of similar construction have been in use. I therefore do not claim such a combination. broadly; but

Vhat I do claim as my invention, and desire to secure by Letters Patent, is-

In a lubrieator, the combination, with the lower part, B, having formed integral therewith the upright b, provided with channel h, channel fr', and condensing-chamber k, and the glass body A, supported by said lower part ofthe top piece, C, having a chamber, k2, and the plug D, having the chamber 7." communicat ing with the chambers k2 and k,substantially as and for the purpose specified.
